I agree, before she seemed cheerful and I was starting to think she's different from all the other like evil sisters in other stories, but after these last few chapters I'm gettin the vibes she might be up to something. I reeeeeeeeeeally hope she's not a closet bitch though, I need straight up loving sister bonds, not 'I'll act like your sister but really scheming your demise' sister
Maybe she's possessed
That'd be an interesting twist, like if she's possessed by that one demon dude she keeps dreamin about so he can get close to her or something.
Did they explain why she was neglected and became fat like she wasn't fat when she was young nor ugly they were twins
Idk why but the sis kinda sus or am I'm paranoid because I read too many sus characters ╮(￣▽￣)╭
